Ammonia is a colorless gas made of nitrogen and hydrogen with a strong and distinguishable odor that occurs naturally in air, soil, and water and is also a by-product of the normal biological processes of humans and animals.
Ammonia is poisonous if inhaled in great quantities and irritates the eyes, nose, and throat in lesser amounts.
Ammonia Scrubbers remove pollutants via a chemical reaction as opposed to Particulate Scrubberswhich inject liquid into the gas stream. Ammonia Scrubbers have proven to be very effective at removing the ammonia from exhaust streams using this method.
In the case of Ammonia Scrubbers, dilute sulfuric acid (H2SO4) is typically used to neutralize the ammonia. The resulting byproduct, a form of salt, is collected and removed through the wastewater blow-down, as the treated air stream is exhausted through the stack.
Efficiency is critical for Ammonia Scrubbers. Due to its toxicity, ammonia gas is a regulated compound that needs to be treated below established limits before it is released into the atmosphere.
For Ammonia Scrubbers to work properly, they must fit the application at hand. A number of variables can be involved, including:
- The presence of other chemicals or particulates in the exhaust stream
- The temperature and flow rate of the waste stream
- The initial concentration of the ammonia in the waste stream.
- Can handle high temperature streams
- Processes high moisture streams
- Smaller space requirements
- Can be retrofitted into current equipment (in some cases)
- Provides cooling of heated gases
- Higher removal capabilities than other equipment
- Lower cost of purchase
- Can remove gases and particulates, in a single unit
- Able to neutralize highly corrosive gases and dusts
- No secondary dust source
- No temperature limits
- Can handle highly flammable dusts, with very little risk of explosion
- Several customizable options, based on specific output and applications, often allowing for a reduction in cost.
